SET OF INTERACTIVE CELLS FOR GROUPS OF MULTIPLE USERS INTEGRATED BY DISTRIBUTED COMPUTING
SYSTEMS
Technical Field
[1] The present invention relates to the technical field of constructive systems and arrangements applied in electromechanical and digital interactive devices integrated by digital systems for presentation, interaction, synchronization and control for use in several environments such as stands, domes, kiosks, inflatable tents, classrooms and meeting rooms, and other facilities used in fairs, events, commercial centers, in which applications may take place in several areas, such as providing training, education, entertainment and other purposes.
Background Art
[2] There are several devices in backgroundart aiming to achieve maximum interaction with user, so as to provide ergonomic and functional features, such as positioning of the game table, positioning of the viewing screen, and easy access to decision making for groups of people, so as to assure a complete integration between users and training means, education, entertainment, games or advertisement.
[3] Several documents describe systems and methods to provide online interactive games, e. g. International Publication no. WO 01/41447. In this document, an experience of online game through cable television broadband network comprised of a terminal server and terminals for players with display is described.
[4] International Publication no. WO 95/33340 describes a visualization system and method for three dimensional exhibition in order to stimulate the participation sensation of the spectator. The visualization system is comprised of a main screen and two secondary screens, arranged so as to produce together the view of a three dimensional image.
[5] Patent no.

Technical Problem
[6] The solutions mentioned in above documents and other existing in background, as
can be verified, do not conveniently and efficiently solve problems existing in device and system platforms aiming to provide an appropriate environment for providing training, education, entertainment, and other purposes.
[7] The systems used in online games known in the background art do not allow presence interactivity among players, since players stay each in a different terminal and in some cases, such as the one described in document WO 01/41447, the players are in isolated environments.
[8] Immersion systems, as the one described in document WO 95/33340, do not provide user with the immersion needed and appropriate for its purposes due to the lack of an interactive device between means and user groups.
[9] Mobile platforms and dome projection such as the ones described in document US
5,192,247 do not provide users with better immersion due to the lack of an interactive interface.
Technical Solution
[10] The objective of the present invention is therefore to provide maximum interaction with users for a low cost.
[11] Another objective of the present invention is to provide a bigger and more appropriate immersion of the users, so as to assure complete interaction between users and training means, education, entertainment, games or advertisement.
[12] In order to achieve above mentioned objectives, solving technical problems existing in background art, the present invention discloses systems and constructive systems and arrangements applied in electromechanical and digital interactive devices integrated by digital systems for presentation, interaction, synchronization and control.
[13] Basically, the technical solution employs a platform of mechanisms comprised of: at least two interactive cells with devices such as translucent screens with vertical projections and relatively horizontal tables with electromechanical keyboards covered by a projection screen; and at least one translucent central projection screen. This set of cells and central screen is arranged in 1C so that the concave side of 1C allows, through image projectors, the exhibition of synchronized combined images or independent images, and the convex side allows the exhibition of synchronized combined images or independent images which, in conjunction with the horizontal tables, provides interactive action of the user. Due to the arrangement in 1C, users in determined convex end, around the table, do not view the vertical screen of the users in the other end.
[14] Said arrangement of elements and devices is controlled by a process of data exchange, synchronization, collaboration and control of these devices through a distributed computing system, which is associated to other mechanisms to a data network, illumination automation system through reflectors and light robots, smoke machines, presence sensors and monitoring cameras.
Advantageous Effects
[15] The arrangement of screen so as to form images in a visual field of 120 degrees or more to the phase of immersion of the interactivity associated to a high quality sound system provides larger immersion, important for the visiting public. The subsequent movement of the users in environment, interacting via personal potable devices with interactivity cells, enables a novel group dynamic in the field of interactive spaces. In the interactive steps with surfaces sensitive to touch of hand, such as interactive surface table, a collaborative work and collective decision making device is provided. As in the embodiment in 'L', the plan for vertical visualization allows the presentation of high quality visual media, the group of users can experiment a very rich interactivity through this embodiment.
[16] The positioning of another group of users separated only by a screen for vertical exhibition has the objective of not allowing participants to see the other group's content, but with visual and verbal contact among parts.
[17] Such embodiment, for example, improves the competition among groups.
[18] The process of data exchange, synchronization, collaboration and control of the interactive space devices allow the transparent integration of applications for multimedia, collaborative work tools, voice and image recognition and interactive surfaces with the user.
[19] A specialized application allows the previous edition of the experience to be generated, programming media sequences and goals to be achieved by users in interaction with other users. For example, users can play the character from a multimedia game, by signing up, which may take place by images of the users inserted in characters, through a digital camera connected to a computer, accessing a database appropriate for this purpose.
[20] Also, high quality audiovisual devices assure the immersion of the users to the content of the event.

Mode for Invention
[26] In accordance with referred illustrations, the present invention is comprised of a set
of interactive cells for groups of multiple users integrated by distributed computing systems.
[27] The space is comprised of at least two interactive cells (1), an exhibition screen (2) and synchronization and control systems.
[28] The interactive cells (1) allow the interaction in groups of multiple users through a screen for vertical exhibition (3) and a table with interactive surface (4).
[29] Screens (2) only for exhibition are arranged among cells to avoid the decision made by group to be seen by other groups. And the arrangement of this set of cells (1) and scren (2) allows the integration among groups, improving the immersion of the users in the middle. Also, both screen (2) among cells and the screens (3) of the cells (1) are translucent, allowing exhibition to be viewed in both sides, for example, a film or animation, without needing the employment of additional projectors. Additionally, the embodiment approximately in 1C of the set of cells (1) and the screen (2) between cells is determined with an angle providing a field of vision of 120 degrees or more and dimensions around 2,5m high and 1,875m wide, so as to optimize the use of the sp ace without any amendments between the exhibition screens.
[30] In the concave area formed by screens (2) and (3) synchronized projectors (5) are fixed in an upper support (not shown) to project the images on translucent screens (2) and (3) allowing the visualization of both sides of the screen. While in the convex area only the projectors (6) over each table (4) are fixed in an upper support (not shown). Due to the dimensions of the environment, the projections over the tables (4) may be performed with the help of a mirror (7) positioned over each table. The projection over the screens (2) and (3) is integrated, allowing for example the exhibition of the same image in both screens (3) of the cells (1), of images formed on screens (2) and (3) together or images moving between screens (2) and (3). Also, high quality sound devices (8) are arranged assuring the immersion of the users with the content of the event.
[31] In order to provide the complete interaction and immersion of the users in the space of experience, two software are employed, one for synchrony and other for control of the event.
[32] Also, the interactive table (4) is comprised of a robust sustentation structure, actuation keys and a micro controlled electronic circuit.
[33] Additionally, in accordance with the event, cells (1) and screens (2) may be employed in several embodiments. For illustrative and non restrictive purposes, figures presented show the embodiment with two cells (1) and a screen (2).
[34] The software for controlling the decision making table interprets the status of the keys on each table and manages the images to be projected on the screen and over the tables according to the program of the event.
[35] The process of data exchange, synchronization, collaboration and control of the devices of the interactive space is provided through software acting over the interactive set.
[36] The interactive set is comprised of several hardware and software resources through a distributed software infrastructure, being responsible for the integration of the resources through a communication model and a process of data exchanging. The integration alternatives are presented according to the interfaces available in hardware devices and applications.
[37] The integration of software and hardware resources through a software infrastructure uses the concept of agents, through a standardized interface and a set of attributes, providing the interoperation of the agents and the programming. The agents may be distributed to several computers, configuring a network of agents that may be accessed through remote method calls, or through event structured messages.
[38] As presented in Figure 4, the support of the network of agents configured makes four steps available: services of name and disclosure, agent loader and configuration management, data persistence, and service of events, wherein these steps are configured according to the interactive event performed.
[39] The service of name and disclosure uniquely registers each agent and attributes in a name and directory server allowing an easy localization of other agents through their names and attributes.
[40] The agent loader and configuration management controls the distribution of agents to the computers and the way it is loaded.
[41] The data persistence registers in a database the persistent agent attributes, such as the name of the communication port with a device or the configuration of the keys from a remote control.
[42] The service of events performs the exchange of asynchronous information between the various agents through an advertisement-subscription model. AU the agents are automatically producers and consumers and only need to declare what they want to perform, advertising types of events they generate and subscribing events of interest, respectively.
[43] In order to enable an infrastructure that might enable to access all hardware and software resources transparently, the integration must be performed through standardized agents and interfaces, providing an interoperation, defining the access to attributes and the encapsulation of the communication interfaces with hardware devices and applications. Also, this agent model makes the resources share all the services offered through the integration with software and hardware.
[44] The presentations are controlled by a presentation management agent. This agent manages the loading and unloading of presentations and the connection with the
interface with the user. This interface with the user is performed through an agent that obtains information from the manager and allows to choose the presentation and command the evolution of the interactive event.
[45] The modeling of the present invention allows the execution of complex presentation contents through a graphic language to define sequential behaviors, providing non linear flows, parallelisms and leaps during the execution of the content.
[46] In order to enable the debugging and monitoring of the interactive event space, even with the devices working independently and applications being applied parallelly, log and monitoring tools are disclosed. The log is centralized and, besides conventional resources, it allows various levels of notice and also habilitates to log an application only through a configuration file. The monitoring allows to view the inputs regarding the agents in directory service; to control the basic interface of the agent, through initialization, configuration and stop; visualization of the attributes of each agent; monitoring of producers and consumers in event service; logging all the events of the applications; performing broadcast of any event for debugging; and following up the presentation in run.
[47] Additionally, the software provides the voice and image recognition in the interactive space through specific libraries allowing the remote run of functions such as luminosity and projection control in exhibition screens (3) and (4).
[48] Besides the interactive surfaces above mentioned, the software may integrate other devices such as floors with interactive surface.
Industrial Applicability
[49] The set of cells of interactive devices disclosed in the present patent application may be reproduced in any type of industry having appropriate technologies for producing electro-electronic and mechanic devices associated to computational technologies, with various applications in various technical fields, such as providing training, education, entertainment, games, publicity, marketing and other purposes, in special experience marketing; in which uses may take place in several environments, such as stands, domes, kiosks, inflatable tents, and other facilities used in fairs, events, commercial centers.
